BMW X5 vs Mitsubishi Eclipse Cross: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Mitsubishi Eclipse Cross burns about $2,300 of fuel annually against $2,900 for the BMW X5. That $600 yearly gap compounds to roughly $3,000 over five years and $4,800 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City versus highway split: the Mitsubishi Eclipse Cross is the stronger commuter at 26 mpg city, while the BMW X5 pulls ahead on the interstate at 31 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.

Powertrain choice: the BMW X5 is recorded with 4 distinct engine configurations (SIDI & PFI; Mild Hybrid, SIDI; PHEV, SIDI; Mild Hybrid), the Mitsubishi Eclipse Cross with 1 (SIDI). Across 61 recorded BMW X5 configurations and 28 for the Mitsubishi Eclipse Cross, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the BMW X5 is offered with All-Wheel Drive, Rear-Wheel Drive, the Mitsubishi Eclipse Cross with 4-Wheel Drive, Front-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the BMW X5 emits 130 g/mile of CO2 versus 327 g/mile for the Mitsubishi Eclipse Cross. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
